Hello,
anyone have a Rust Code that work with Waveshare E-INK Display 1.54" V2
( Jumper 4 Line )
Got only this:
Wireing:
Using: XIAO ESP32S3 + Wio-SX1262
| Panel pin | XIAO pin | GPIO | Notes |
|---|---|---|---|
| VCC | 3V3 | — | 3.3 V only |
| GND | GND | — | |
| DIN | D10 / MOSI | 9 | shared with the radio |
| CLK | D8 / SCK | 7 | shared with the radio |
| CS | D1 | 2 | |
| DC | D2 | 3 | |
| RST | D3 | 4 | |
| BUSY | D4 | 5 | |
The Display works, got a ARDUINO Code
that do a Demo and this works.
But wanna use RUST
/*
* E-Ink Diagnose mit GxEPD2 (v6)
* Seeed XIAO ESP32-S3 + Waveshare 1.54" e-Paper V2 (200x200, UC8151)
*
* VORHER INSTALLIEREN (Bibliotheks-Manager, "Werkzeuge -> Bibliotheken verwalten"):
* - "GxEPD2" (von Jean-Marc Zingg)
* - "Adafruit GFX Library" (wird von GxEPD2 benoetigt)
*
* Verkabelung (XIAO ESP32-S3):
* VCC -> 3V3
* GND -> GND
* DIN -> D10 (GPIO9, MOSI)
* CLK -> D9 (GPIO8, SCK)
* CS -> D1 (GPIO2)
* DC -> D2 (GPIO3)
* RST -> D3 (GPIO4)
* BUSY -> D4 (GPIO5)
